Abstract
A system and method for secure communications in a communication system, wherein the system programs a computer to perform the method, which includes: receiving at least one authentication key, without an encryption key, from a key-management server; receiving a packet, which is encrypted, from a source device; authenticating the packet, using the at least one authentication key, without cryptographically altering the packet; and forwarding the authenticated packet to a destination device of the packet.
